Understanding Irrigation Fittings: A DIY Guide

Before diving into your irrigation project, you’ll need to understand the basic components that make up a functional system. Irrigation fittings are the essential connectors that join pipes, control water flow, and direct moisture to your plants. These small but crucial parts come in various materials including PVC, polyethylene, and brass, each suited for different applications and water pressures.

When selecting fittings, you’ll need to consider compatibility with your water source, pipe dimensions, and the specific watering needs of your garden. PVC fittings offer durability and affordability for permanent installations, while polyethylene options provide flexibility for systems that may need seasonal adjustments. Brass fittings, though more expensive, deliver superior longevity and strength for high-pressure applications.

Understanding basic fitting types is fundamental to your project’s success.
